GAS MIXER FOR INTERNAL-COMBUSTION ENGINES.

Application filed February 26, 1921.

To all whom it may concern:

Be it known that I, Bnnrono C. WYsoNc, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Gas Mixer for Internal-Combustion Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in whlch like numerals refer to like parts.

This invention relates to a gas mixer for the intake of an internal combustion engine and is adapted to be interposed between the intake manifold and the carbureter.

The chief object of the invention is to provide a mixer which will break up further the volatilized fuel and thoroughly mix the same after said fuel has been discharged from the carburetor into the intake.

The chief feature of the invention consists in the particular means for mixing the fuel and the positioning of the same in the intake.

Another feature of the invention consists in the particular mounting of the mixer, whereby the same may be readily associated between the carburetor and intake connections'so as to constitute a gasket between the companion flanges of said connections.

Another feature of the invention consists in the particular construction of the mixing element.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Fig. l is a side elevational view of an internal combustion engine of a motor vehicle including a carburetor and showing the invention associated there with. Fig. 2 is a plan view of the invention detached from the internal combustion en gine. Fig. 3 is a central cross sectional View of the invention taken on line 3-3 of F ig.-2.

In the drawings 10 indicates an internal combustion engine having an intake manifold 11 and an intake pipe 12 with which is associated a carburetor 13. The intake 11 and pipe 12 are provided with comp-anion flanges 14 which are secured together by means of the bolts 15 to rigidly secure the carburetor to the intake of the internal combustion engine.

The mixing device constitutes an attach- Serial No. 447,983.

ment for the foregoing and comprises a gasket body portion 16 of substantially elliptical form provided with a pair of bolt openings 17 along the major axis. Centrally positioned in said elliptical body por-' tion is a central opening 18. It is to be un derstood that'the central opening 18 registers with the carbureter discharge opening and the intake opening, and the gasket 16 is substantially the same shape in outline as the companion flanges 14 such that the gas; ket registers with said companion flanges and is adapted to be positioned therebetween by means of the bolts 15 passing throu h the registering bolt openings 17 such that when said bolts are tightened, the gasket body portion will be rigidly secured between the carburetor and the intake of the engine.

The mixing element is rotatably supported by the elliptical body portion and herein is shown comprising a circular plate with a serrated edge and, is provided with bent tips 20 shown in cross section in Fig. 3 so as to increase the propeller action thereof. The central portion of the plate 19 is perforated or foraminated by means of a plurality of small holes 120. It is to be understood that the curved and foraminated plate 19 is rotatably mounted so as to revolve about one of its diameters. It is to be further understood that the rotatable mounting may be positioned anywhere within the central opening 18 of the elliptical gasket 16. The rotatable mounting preferably is along or coincides with minor axis of said elliptical gasket.

Herein the preferred means for rotatably supporting the perforated and curved mixing plate comprises a spindle or shaft 21 which may or may not be rigid with the plate 19. Said shaft or spindle is provided with conical points 22, and there is provided in the body portion 16 conical seats 23 for said conical points-22. In the present invention said seats are formed in the end of a bolt 24 having a threaded engagement with the gasket 16 in the opening 25 thereof. The bolt 24 is adjusted along the minor axis by means of the screw head 26 and a lock nut 27 rigidly secures said bolt in the adjusted position.

It is to be understood that as illustrated the preferred form of the invention is such that the bands in the tips of the plate do not exceed in width the thickness of the gasket 16 such that the device may be inserted as a unit between the companion flanges 14 and readily secured thereto with but little difiiculty.

The invention claimed is:

1. A gas mixer for the intake of an internal combustion engine, including a body portion having an opening registering With said intake, a plate rotatable about its diam, eter having a plurality of perforations in the central portion thereof, and means for rotatably supporting said plate Within said body portion.

2. A gas mixer for the intake of an internal combustion engine, including a body portion having an opening registering withsaid intake, a plate rotatable about its diameter having a plurality of perforations'in the central portion thereof, and adjustable means mounted in said body portion for rot'atably supporting said plate therein.

3; A gas mixer for the intake of an internal combustion engine, including a body portion having an opening registering with said intake, a circular plate rotatable about its diameter having a plurality of perforations in the central portion thereof, and adjustable means for rotatably supporting said plate in the opening of said body por tion, the axis of rotation of said plate extending diametrically therethrough at right angles to the directlon of flow of the gas passing through said opening.

In witness whereof, I have hereunto affixed my signature.

BEDFORD C. WYSONG.
